"Let's sleep tonight." "I still want to enjoy our life together." Rei wants to have children and have sex, but she is living a sexless and frustrating life. One day, a new drug arrived at the hospital where she works, and the doctor gave her instructions on how to handle it. "We imported a drug that improves natural healing power. However, it also improves sexual function dramatically, so don't give it to patients yet." Unable to suppress her throbbing body, Rei steals the drug and gives it to her patient. She attacks the patient who is still in agony with an erection, and when she makes him cum inside her while riding her, she feels an indescribable orgasm from the climax and increased sexual desire that she has never felt before. The aphrodisiac causes a new chemical reaction through the man's body. The slutty nurse who replaces semen with aphrodisiac sperm left in her pussy is looking for the next patient to have sex with today.
